It’s also worth noting that even if alternatives superior to agar were found, scientists are reluctant to abandon established protocols (even when microbiologists do use other jellies, they often still add agar to the mix, for example, to increase the gel strength of the solid media). As agar has been the standard gelling agent in microbiology for around 150 years, an enormous infrastructure of standardized methods, reference values, and quality control procedures has emerged around its specific properties. Switching to a different medium (even a superior one) means results may not be directly comparable to decades of published literature or to other laboratories’ findings.
Altman 的这番话，看上去合理，但也有明显的逻辑谬误。人类确实要吃喝 20 年才能「变聪明」，但这 20 年的能量消耗是基线生存，用来维持生命、维持社会运转，不是专为「产生智能」而额外投入的。哪怕一个人一辈子啥都不学，躺平当咸鱼，他也得吃饭喝水呼吸。
